GFpECPointGetSize

Gets the size of the
IppsGFpECPoint
context of a point on an elliptic curve.

Syntax

IppStatus ippsGFpECPointGetSize(const IppsGFpECState*
pEC
, int*
pSize
);
Include Files
ippcp.h
Parameters
pEC
Pointer to the context of the elliptic curve.
pSize
Buffer size, in bytes, needed for the
IppsGFpECPoint
context.
Description
This function returns the size of the buffer associated with the
IppsGFpECPoint
context, which you may use to store data for a point on the elliptic curve over the finite field.
Return Values
ippStsNoErr
Indicates no error. Any other value indicates an error or warning.
ippStsNullPtrErr
Indicates an error condition if any of the specified pointers is
NULL
.
ippStsContextMatchErr
Indicates an error condition if the
IppsGFpECState
context parameter does not match the operation.
